Can't access uploaded CRG albums


I’ve been using CE4 Client Response Gallery for many years, though not the past 2 years. Now when I’m uploading galleries through Lightroom as I have done before, I can’t access them after upload. I get the following error in chrome:
“Fatal error: Uncaught Error: Call to undefined function get_magic_quotes_gpc() in /customers/b/a/a/ Stack trace: #0 /customers/b/a/a/ require_once() #1 /customers/b/a/a/ require_once(’/customers/b/a/…’) #2 {main} thrown in /customers/b/a/a/ on line 15”.

I have tried to figure out what is wrong through this forum but I’m lost. Maybe there’s been updates to CRG which have made my versions too old?
I have no Backlight-folder on my server, only a ttg-be-folder. My last purchase was “Backlight 2 x 1” back in Nov 2018. Can anybody help me get up and running with the Client Response Gallery again?

The CE4 version of CRG is no longe4 supported.
You’ll likely need the Backlight version of Client Response. If you don’t have it already, you may need to update to BL 4.

Ok thank you! I have Backlight 2, will Client Response work with version 2 or do I need Backlight 4?

you’ll need BL4
